MUSIC-ROLL HOLDER.

Specification of Letters Patent.

Patented July 161 1907.

Application filed April 27, 1907. Serial No. 370,599.

To all whom it may concern:

13e it known that I, GEORGE HOWLETT Davis, a citizen of the UnitedStates, residing at West Orange, in the county of Essex and State of NewJersey, have invented new and useful Improvements in Music-Roll Holders,of which the following is a specification.

My 'present invention relates to certain new and useul improvements inmusic roll' holders especially designedfor use in connection with playerpianos and' pianos having automatic playing attachments associatedtherewith.

The primary object of the invention is to provide a novel constructionof roll holder designed to be movably mounted under the key-base oi themusical instrument in such manner that the holder may be' moved ,hackunder the key-base'so as to be out of view when base when in operativeposition so as to cause the music sheet to travel in a nearly verticalplane.

The invention has for a further object to. provide a winding andrewinding the music sheet.

Briefly and generally stated the invention emnote selecting deviceandthe take-up roll at its front end, and a swinging frame pivotallyconnected to the sliding element and designed to be swung upward atright angles'thereto in front of the key-base and also designed-.to beswung parallel with said sliding element .and then moved back under thekey-base where it will be out oiview and out of the way.

The invention furthercornprises the construction winding and rewindingthe music-sheet.

A preferred embodiment of the invention is illustrated in theaccompanying drawing`whcrein Figure l, is a side elevation of themusic-roll holder shown in playing position on the key-base of a piano,the said key-base being shown in scction-Fig. 2, is a similar elevationshowing the holder moved aback under the key-base-Fig 3, is a detailside elevation showing electric note selecting device. Fig. 4, is adetail top plan view partly in section of one 4slide ofthe holdershowing a Apart of thc winding and rewinding mechanism for themusicsheet. Fig. 5, isa front ele-'v vation looking in the direction'of thearrow X-Figl. Fig. 6, is a horizontal sectional view of the winding andrewinding mechanism.

Referring to the drawing. the refercnceinumeral 1 designates thekey-board base of anordina-ry ano having a self-playingmechanismvassociated therewith...

end of, which is secureda tracker 4, having the usual air ducts andVfrom which lead the air tubes 5 usually vin Fig. 6.

in the form of rubber pipes which communicate with the operatingpneumatics. Secured to and depending from opposite sides of the plato 3in rear of the tracker 4 are two brackets 6 in which is journaled a maindriving shaft-7 which may be rotated clockwise as seen from the righthand side shown in Figs. land 2 by any suitable mechanism. 'Alsojonrnalcd in the brackets at the forward ends thereof is a transverseshaft 8 carof which are joined together by means of the curved guardplate 14 said arms carrying respectively the end bearings 15 for thedclivery.or music -spool 16, some of said bearings being of the usualwinged typo to receive the corresponding wing-journal on the music spoolThe end bearing 15 for the music spool, which it will be understood isjournalcd in one of the arms 13 is provided at its outer end with asprocket wheel 17 and a handle extension 1.8 which sprocket wheel isgeared, through the medium of a sprocket chain 19, with a-sprocket wheel20 journaled on the shaft 8. Formed integral with the sprocket wheel 2()is another and smaller sprocket wheel 21 geared by means of a sprocketchain 22vwith another sprocket wheel 23 car- Y ricd by sleeve 24, whichsleeve is loosely mounted on the driving shaft 7, said sleeve being holdagainst longitudinal movement on, the shaft 7 by means of a key' 25which may project within an annular groove formed in the periphigry ofthel sleeve, as more clearly shown The driving shaft 7 isVlongitudinally movable in its bearings and has -secured to one endthereof a handle` 26 by which ity may be shifted longitudinally and aclutch member 27 designed to he brought into engagement witlraco'perating clutch member 281cm the' sleeve 24 when said shaft isl movedlongitudinally in the direction of the arrow Fig. 4.

plate 3 asshown in Fig. 2, the armsbeing held in the position shownv byany suitable retaining-device as for Iinstance 1- spring 29 asshowninvFigs. l and 2. When n this` position the music roll holder will-be out of view and out'of-the'way oi a performefwhen seated at :thepiano When it is desired to bring the music roll h'oldcrin position foroperation the slide 3. is drawn ont until' the tracker 4 assumes aposition in front o f the 'key-boardjvbase l, whereupon the arms I3areswung up in the position illustrated in Fig. 1 where it will 2' InCombination with the key'hase of a piano a mem' be seen that the musicspool 16 will be directly in front 4of the'key-board and the musiclsheet 30 during its travel over .th tracker 4 and onto the take-uproller 9 move in a nearly vertical direction in front of the .fperormerwhen" seated ,at the-piano. The frame V.is

held in its operative position by means of a. spring catch 3]., securedto the plate 3, which catch is designed to be brought intoengagement-with a pin 32, projecting from one o f the arms 13' of theswinging frame.

The take-up roller 9 is driven to wind the music sheet thereon by meansofthe shaft 7, pinion 12 and' l2 out of mesh with the gear\10 bringingthe clutch' elements 27 and 2S into engagement. As the .shaft 7 nowcontinues to' rotate in its clockwise direction rotary motion will beimparted from the sprocket wheel 23 to the wheels 2l and 20 and throughthe latter to thesprbcket wheel 1'7 which will cause the music spool towind in the opposite direction whereupon the music sheet will be rewoundthereon.

In Fig. 3 I have shown the invention asapplied to playing mechanismcontrolled electrically 4instead of pneumatically and instead ofemploying the ordinary trclel' 4 Ahaving the usual wind ducts,-I employan electric selecting device embodying a contact roller 42 joturnaled inarms 33 projectingoutward from the plate 3, and selector-fingers 34which coperate with the contact roller 42, said selector-fingers beingcarried by a rail 35 secured in position by means of arms 36 attached tothe swinging arms 13.

I do not wish to be undei'stood as limiting myself to .the preciseconstruction and arrangement of parte herein shown and described exceptas I may be so limited by the terms ofthe appended claims, as 1am awarethat changes and additions may be made in the construction herein shownand described without departing fromthe spirit of the invention.

Obviously any arrangement of mechanism may be --employed with myimproved music roll holder for winding and rewinding the music sheet,that shown being only by way of example. The principal feature of theinvention resides in a music roll holder embodying s sliding memberarranged to be moved back and forth-beneath the'key-board bose of thepiano, said sliding member carrying a swinging frame'provided with endbearings for a music spool, said sw ngivng frame being designed when thesliding member'is in its outer position, 4to assume aposition infront ofthe key-board base Vand also designed to assumes. position beneath andparallel with the sliding, memberl and adapted to be moved underthe-key-board base where the holderwillbe outof viewsn'doutof the way.'
